Abstract

For improving the humidity resistance reliability and the jitter property of an optical disk, the adhesive layer used for bonding a bonding type optical information recording medium is defined such that the glass transition temperature is 100 DEG C or higher at 200 DEG C or lower, the modulus of elasticity at 25 to 80 DEG C is 1000 Mpa or more, the adhesion strength thereof is 4N or more, the reflective layer is defined such that the hardness is 60 mgf/ μm<SP>2</SP> or more as the nano indentation hardness, and the dye recording layer is defined such that the water solubility of the dye as light absorption is 0.2 or less.
